I'm simulating a 2D U-bend duct using FLUENT.
Properties from experimental case are; U= 31.1m/s. Mach= 0.1. Operating Pressure= 12atm. Re=10^6. What are the boundary conditions at inlet and outlet? |

If you don't know where and how the values were measured, I would try a velocity inlet with a bulk velocity of U and a pressure outlet at the operating pressure.

As far as I know you do not need to specify a value for pressure at a velocity inlet.
The pressure at the inlet will be a result of your simulation. |
